Start by chopping the cooked chicken into bite-sized pieces, ensuring they are well-cooled to maintain freshness.

Next, core and dice the apple into small chunks.

Finely dice the red onion.

In a large mixing bowl, combine the chopped chicken, apple pieces, diced onion, and dried cranberries. Gently fold the ingredients together.

In a separate bowl, whisk together mayonnaise and plain yogurt until smooth. Add Dijon mustard, red wine vinegar, salt, and black pepper. Whisk until combined.

Pour the creamy dressing over the salad mixture, and mix until all ingredients are coated.

Serve immediately or refrigerate for about 30 minutes before serving.
